MathComp/MathFun is the CIE/USA-DFW flagship youth program. MathComp provided the opportunity to the students in Grade 1 to 7 to demonstrate their math problem solving skills. MathFun was an interactive program allowing parent/children to work together in solving math quizzes and games which stimulate the students’ interest in mathematics. Every year dozens of local non-profit organizations, educational organizations, university/college organizations, sponsors, and after schools participated in the MathFun activity. The activities they brought included math puzzles and games, sudoku, chess, science projects, math education and robotics. While the students are working on their competition, we offer Parenting Seminar to provide general suggestions to the parents in providing guidance to their children to succeed in the STEM subjects.
